Claude of Duty: Vibe Slops II
The Black Ops II port itself, in the copy that survived the takedown: a fan's GitHub Pages copy of the September build. Hijacked only, free-for-all to 30 against six bots, about 34 MB. It may be taken down too.

Call of Duty in Your Browser: What Happened, and What to Play Instead
Short answer: yes, in an older copy. The two Call of Duty browser ports on our wall, Claude of Duty: Vibe Slops II (Black Ops II multiplayer on Hijacked and Nuketown 2025) and a Black Ops III Zombies port of the Cheese Cube map, went offline on October 10, 2026. Their creator, Luckey Faraday, says Activision sent a DMCA notice and every one of his Call of Duty browser ports is gone. A fan's copy of Claude of Duty from early September still runs: Hijacked only, against six bots, and it may be taken down too. Cheese Cube has no working copy that we know of. These free shooters also run in a tab today, with bots or real players and nothing to install.

If you came for Black Ops multiplayer 7
The Black Ops II port itself, in the copy that survived, then shooters with the same pick-up-and-frag loop: matches against bots when nobody is on, or real players online.
Not Halo
The nearest thing to a modern console shooter on the wall: Halo-style maps like Blood Gulch, Guardian and Lockout, Slayer and free-for-all, matchmaking, and bot matches when nobody is on. Friends join by sharing a match name.
Combat Skirmish
The real Counter-Strike 1.6 community, thousands of players on public servers: bomb defusal on Dust2 and Inferno, deathmatch and zombie mod. Skip Quick Join and pick a classic server from the list; the site shows ads.
Quake III Arena (q3.pieter.com)
Fast online deathmatch with real players: type a name and you are in, The Longest Yard included. About 76 MB the first time, cached after.
Redcoats.io
Large-scale war with hundreds of real players, musket era: hold the line as infantry, charge as cavalry, man the cannons and take the forts.
Undersphere
A quick online FPS on a tiny planetoid where gravity pulls to the core, so opponents run along the curve; bots fill the server.
Quake II (q2.pieter.com)
Deathmatch and capture the flag for up to eight, topped up with bots, so there is always a match.
If you came for Zombies 4
We don't know of a working Call of Duty Zombies port in a browser, but Nazi Zombies: Portable is a fan remake of the original World at War mode, built from scratch. For more waves, upgrades and co-op:
Nazi Zombies: Portable
The closest thing to classic Call of Duty Zombies in a tab: a fan remake of World at War's Nazi Zombies, built from scratch with its own art. Hold the Nacht der Untoten bunker as zombies break in through the windows, round after round. About 96 MB, so give it a minute and a half.
OVERRUN: Dockyard Nine
Survive escalating waves of combat synthetics in a neon-industrial dockyard, with explosive barrels and headshots. Use a mouse and headphones.
Hexfall
Co-op survival for up to eight players: cast spells, buy upgrades between fights and take down a boss. The upgrade loop is the Zombies part.
SandStorm
Waves of enemies in a world where every grain of sand is simulated: dig in, blow holes in the ground, then plant the nuke. Co-op rooms.
Classic shooters that still run in a tab 11
The shooters Call of Duty grew up on, ported to the browser by their communities: Counter-Strike 1.6 on live servers, Quake I to III online, Wolfenstein 3D, Doom, Duke Nukem 3D, Descent, Valve's free Half-Life demos and Counter-Strike-style bunny hopping. Filter by phone, players or download size.

Questions
Can you play Black Ops 2 in a browser?
Yes, in an older copy, as of October 12, 2026. Claude of Duty: Vibe Slops II is the one that works: its creator's site, with Hijacked, Nuketown 2025 and private rooms for friends, now shows only his DMCA announcement, but a fan's copy of the September build still runs on GitHub Pages, with Hijacked against six bots. Our listing links to that copy. It may go offline too.
What happened to Claude of Duty?
On October 10, 2026, Luckey Faraday posted that Activision had sent a DMCA notice over his Call of Duty browser ports, that his posts about them were removed, and that every game was offline. A fan (Froydinger) had forked the code on GitHub on September 8, and that copy still plays; our listing points to it and says so. We list games and link to them; we never hosted it.
What about Cheese Cube and Black Ops III Zombies?
The browser port of the Cheese Cube Zombies map was offline too when we checked on October 10. Its old address now forwards to an unrelated registration website, so be careful with links that still claim to have it. Our old listing explains what it was. For round-based zombies that work today, try Nazi Zombies: Portable.
Will they come back?
We recheck both. Claude of Duty is back on our wall through the fan copy as of October 12, 2026; if the creator's own site returns, we will switch to it. Cheese Cube stays off until a working copy turns up.
Which of these work on a phone?
Claude of Duty: Vibe Slops II, Not Halo, Quake III Arena (q3.pieter.com), Redcoats.io, Undersphere, Quake II (q2.pieter.com), SandStorm and Quake (q1.pieter.com) play by touch. The rest want a keyboard and mouse. More in our guide to browser games on your phone.
Do I need an account or a download?
No download for any of them: each runs in the browser tab. No account either, except on Redcoats.io and bunnyhop.lol, where a free account is optional and only saves your progress.
